Barr says Justice Department and Mueller sparred over "legal analysis" in Russia report

In an exclusive interview with "CBS This Morning," Attorney General William Barr says special counsel Robert Mueller could have said whether he believes President Trump committed a crime. CBS News chief legal correspondent Jan Crawford traveled with Barr to Alaska, where he is listening to the unique concerns of native Alaskans. She pressed the attorney general on issues ranging from obstruction of the Russia investigation, to his review of how that probe began in 2016.
